# 

# This Python example illustrates how to create an fcurve and set it as Locked

# 

# We try to import the Softimage constants from win32com.client. This assumes that

# the makepy.py utility has been used on the Softimage type library files (.tlb);

# this automatically installs the Softimage constants into win32com.client.constants

# 

from win32com.client import constants

from win32com.shell import shell

import pythoncom

# Define constants

try:

	siInfo = constants.siInfo

	siStandardFCurve = constants.siStandardFCurve

except:

	# typelib not found

	siInfo = 8

	siStandardFCurve = 20

# Create new scene

null = Application.NewScene("", 0)

# Create a null

null = Application.GetPrim("Null", "", "", "")

# Get the posx parameter from the null

posx = null.posx

# Define some keys

keys = [ 1.00, -5.00, 100.00, 5.00 ]

# Create an fcurve on posx

fc = posx.AddFCurve2( keys, siStandardFCurve )

# Get the current Locked value

ro = fc.Locked

Application.LogMessage( 'fc.Locked before = ' + str(ro), siInfo )

# Set the fc Locked 

fc.Locked = 1

ro = fc.Locked

Application.LogMessage( 'fc.Locked after = ' + str(ro), siInfo )

# Try setting a key when the fcurve is Locked.

fckey = fc.Keys(0)

Application.LogMessage( 'fckey.value before = ' + str(fckey.Value), siInfo )

try:

	fckey.Value = 5.00

	Application.LogMessage( 'fckey.value after = ' + str(fckey.Value), siInfo )

except pythoncom.com_error, (hr, msg, exc, arg):

		# catch the error and print out the error message

		if exc and exc[2]: msg = exc[2]

		Application.LogMessage( "fcurve key set value failed:" + msg)

# Produces the following output: 

#INFO : "fc.Locked before = 0"
